Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed January 20, 1920. Serial No. 352,708.

To all whom it may concern Be it known that I, ABRAHAM NOVICK, a citizen of the United States, and a resident of New York, borough of Manhattan, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Machines for Attaching String to Envelops and the like, of which the following is a specification.

This invention relates to machines for attaching string to envelops and the like and is particularly directed to means for attaching to the bodies or flaps, or both, of envelops or other receptacles made of sheet material, one or more washers, as by means of eyelets, and thereafter affixing a string to the body or flap portion of the envelop by winding that string between a washer and the envelop body or flap as the case may be.

The object of my improvements is to provide a machine of the class specified, reliable in action, efficient in operation and which may be operated at high speed. A further object is to provide a machine in which the envelop is retained in substantially one position during the several steps in the operation.

The machine of the present invention is in the nature of an improvement upon the machine of my copending application, Serial Number 309,436, filed July 8, 1919, to which reference may be had.

To these'ends my improvements comprise features illustrated in their preferred embodiment in the drawings accompanying this specification, wherein Figure 1 is a plan view of so much of a string attaching machine as will suflice to show my improvements. Fig. 2 is a sectional side elevation, the section being taken on line 2-2 of Fig. 1. Fig. 3 is a sectional front elevation, the section being taken on line 3-4; of Fig. 1. Fig. 4 is a sectional plan view corresponding with a portion of what is shown in Fig. 1, the section being taken on line 4.-4 of Fig. 3. Fig. 5 is a sectional front elevation similar to that of Fig. 3, but showing the parts in different relative positions. Figs. 6 and 7 are sectional front elevations corresponding with the major portion of the showing of Fig. 3 and illustrating steps in the operation of my improved machine. Fig. 8 is a fragmentary plan view of a ortion of what is shown in Fig. 3, illustrating a detail of my improvements. line 9-9 of Fig. 8. All the figures of the drawings are to one scale.

Referring now particularly to Figs. 1 to 4 inclusive, my improved machine comprises upper tool-carrying plunger 5, arranged in fixed bearing 9 and actuated for vertical reciprocation therein. Below said plunger 5 are two lower to0l-carrying parallel plungers 6 and 7 arranged in horizontally slidable bearing member 8, in axially fixed relation to each other and actuated in said bearingmember for vertical reciprocation, said plunger 7 being also actuated for rotative movement at suitable times. Said plungers 6 and 7 are adapted for alternate coaction with plunger 5, as they are presented one at a time in coacting position by the sliding movement of bearing member 8.

Said upper plunger bearing 9 is supported from table 11. by opposite legs 10, 10, to the upper portions of which are pivoted levers 12, 13 for operating washer slides 14, 15 respectively. Said plunger 5 is reciprocated vertically at suitable times by means of lever 16 pivoted at 17 in bracket 18 on table 11. Said lever 16 is bifurcated at its forward end. for engagement with and between col lars 19, 20, fixed to plunger 5.

Fixed to bearing 9*and reaching downwardly is stripper plate 60. Said plate has its lower end bifurcated and turned inwardly to straddle the lower end of plun- Fig. 9 is a sectional elevation on.

washer-stack 21 one washer at a time and for presenting that washer in coaxial relation below plunger 5. Upper washer-slide 15 is adapted and actuated for removing from the bottom of washer-stack 22 one washer at a time and for presenting that washer in coaxial relation between the bot tom end of plunger 5 and the washer from slide 14. Eyelets are supplied from time to to the underside of table 11.

30, 31 to t e lower face of table 11 and is actuated for transverse movement, Figs. 1, 2, 3 and 4, by means of lever 32 plvoted at 33 Said lever is bifurcated at its forward 'end, Figs. 3 and 4,

and engages stud 34 fixed to hearing member 8.

Plungers 6 and 7 have their bearings side by side in member 8, in parallelism with each other and with plunger 5 and as said member 8 isrshifted transversely of? the axes of said plungers by lever 32, plungers 6 and 7 are brought alternately into coaxial relation with and below plunger 5; Plunger 5 is provided on its lower end with setting plug 35, and which plug isalso efficient for holding the eyelet thereon by friction after setting. For 'coaction with plunger 5 and its setting plug 35, plunger 6 is provided with anvil head 36, and passing axially there through, needle 37 spring urged upwardly.

For moving said plunger up and down in bearing member 8 lever 38, pivoted at 39 in bracket 40 depending from table 11, is provided. Said lever has oppositeears 42, 43 lying on each side of trunnion block 44 fixed to the lower end of plunger 6. Each of said ears is bifurcated and straddles one of trunnions 45 of block 44. Said bifurcated ears are of sufiicient length to maintain engagement with said trunnions at all times during the shifting of member 8 to and fro in its gibsl Plunger 7 is provided at its upper end with washer receiving seat 46, eyelet anvil 47, and presser ring 48. Said plunger is also provided with axial channel 49 therethrough, and an'gularly disposed channel 50 connectsthe upper part of channel 49 with the outer edge of presser ring 48 for the passageof string 51. For retaining the end of the string, to prevent its slipping back into channel 49, spring clip 52, Figs. 8 and 9, carried by post 61 u standing from slide 8, may be employed. Said clip is also eflicient for holding the end of the string while that string is being wound in place, as will appear later herein.

or reciprocating plunger 7 vertically, rock-shaft 53, having gear 54 in sliding engagement thereon and constrained to rotary movement therewith by key 55, is provided. Said gear engages rack 56 cut in said plunger. It will also be observed that said rack comprlses a series of grooves and rings entirely encircling said plunger so that said plunger is free to rotate while said rack is in constant engagement with said gear, for purposes which will appear later herein.

or oscillating shaft 53 and gear 54 to reciprocate plunger 7, arm 57 fixed to shaft 53 may be actuated to and fro by links 58. For rotating plunger 7 to wind string 51 to its seat, said plunger is provided with sprocket 59 fixed to its lower end, and which sprocket may be connected by a drivin chain, not shown, to a properly governe source of power, not shown herein but which is shown in my hereinbefore mentioned copending application. Also it will be understood that the several levers as 12, 13, 16, 32, 38 and links as 28, 58, may be actuated at suitable times by means well-known in the art but not shown, and very like such as are shown for similar pruposes in my before mentioned application.

The operation of my improved machine is as follows: The. several arts of the machine being as shown in igs. 1, 2, 3 and 4,'eyelet hopper 25 being supplied with eyelets and eyelet 63 being at the delivery end of hopper nose 27, and washers being stacked at 21 and 22, the driving mechanism of the machine, not shown, is started. It will also be understood that string 51 has been su plied in plunger 7 and that the end of t e string has been brought up and out through channel 50, Fig. 2, and delivered into the grip of clip 52, Figs. 8 and 9.

Starting the machine will first cause shaft 53 to oscillate in clockwise direction, Fig. 2, whereby lower plunger 7 will be moved downwardly. Directly succeeding this movelatter part of this movement, washer slides 14, 15 will be advanced, each carrying a washer therewith from the bottom of its respective washer stack, and said slides will position their respective washers one over the other centrally between plungers 5 and 6. At the same time eyelet hopper 25 will be swung on its pivot 26 and nose 27 thereof Wlll position an eyelet below slide 14 concentric with plungers 5 and 6, all as in Fig. 5.

Envelop flap 62 may now be introduced between the forward ends of washer slides 14, 15. Then plunger 6 is moved upwardly until the point of needle 37 enters eyelet 63, whereupon eyelet nose 27 is withdrawn, leaving the eyelet in possession of needle 37. Said plunger 6 continues its upward movement and needle 37 passes through the lower washer. In the meantime plunger 5 descends and its lower end 35 enters the upper washer where it meets the point of needle 37. The two washer slides 14, 15

then withdraw and lower plunger 6, continuing its upward movement, pushes the eyelet through the flap and through the upper washer and sets that eyelet against the flange of setting plug 35, needle 37 being pushed downwardly against its spring, all as in Fig. 6.

Lower plunger 6 now retracts downwardly, leaving the envelop flap held on upper plunger 5 by the friction of eyelet 63 011 setting plug 35. Sliding bearing 8 is now shifted to the right from the position of Fig. 6 to that of Fig. 7, the envelop flap remaining at rest, and plunger 7 is raised into coaction with upper plunger 5, and presser ring 48 lifts those portions of flap 62 adjacent the washers away from the lower washer, whereby room is afforded for the entrance of string 51 between the flap and washer. Plunger 7 is now rotated, preferably in clockwise direction, whereby the string is wound between said flap and washer, preferably for two complete turns. Thenplunger 7 is preferably given a further upward movement sufiicient to give the eyelet a final set, whereby the string is securely clamped in place. Upper plunger 5 now retracts to the position of Fig. 1, whereby the envelop flap is stripped from setting plug 35 by engaging stripper-plate 60, thus completing the operation.
